Science does not stand still, and neither does philosophy, although the latter has a tendency to walk in circles.

How far down the evolutionary scale shall we go? Shall we eat fish? What about shrimps? Oysters? To answer these questions we must bear in mind the central principle on which our concern for other beings is based. As I said ... the only legitimate boundary to our concern for the interests of other beings is the point at which it is no longer accurate to say that the other being has interests. To have interests, in a strict, nonmetaphorical sense, a being must be capable of suffering or experiencing pleasure. If a being suffers, there can be no moral justification for disregarding that suffering, or for refusing to count it equally with the like suffering of any other being. But the converse of this is also true. If a being is not capable of suffering, or of enjoyment, there is nothing to take into account.

I regard Peter as one of the great moralists, because I suspect that more than anyone he has helped to change the attitudes of very many people to the sufferings of animals. Peter is a utilitarian in normative ethics, and a humane attitude to animals is a natural corollary of utilitarianism. Utilitarian concern for animals goes back to Bentham, who, presumably alluding to the Kantians, said that the question was not whether animals can reason, but whether they can suffer.

The only justifiable stopping place for the expansion of altruism is the point at which all whose welfare can be affected by our actions are included within the circle of altruism. This means that all beings with the capacity to feel pleasure or pain should be included; we can improve their welfare by increasing their pleasures and diminishing their pains.

Animal Liberation is Human Liberation too.

Remember Bostrom's definition of existential risk, which refers to the annihilation not of human beings, but of "Earth-originating intelligent life." The replacement of our species by some other form of conscious intelligent life is not in itself, impartially considered, catastrophic. Even if the intelligent machines kill all existing humans, that would be...a very small part of the loss of value that Parfit and Bostrom believe would be brought about by the extinction of Earth-originating intelligent life. The risk posed by the development of AI, therefore, is not so much whether it is friendly to us, but whether it is friendly to the idea of promoting wellbeing in general, for all sentient beings it encounters, itself included.

The core of ethics runs deep in our species and is common to human beings everywhere. It survives the most appalling hardships and the most ruthless attempts to deprive human beings of their humanity. Nevertheless, some people resist the idea that his core has a biological basis which we have inherited from our pre-human ancestors.

Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings.

We are responsible not only for what we do but also for what we could have prevented.

This legible lesson, this ritual recording, must be repeated as often as possible; the punishments must be a school rather than a festival; an ever-open book rather than a ceremony. The duration that makes the punishment effective for the guilty is also useful for the spectators. They must be able to consult at each moment the permanent lexicon of crime and punishment. A secret punishment is a punishment half wasted. Children should be allowed to come to the places where the penalty is being carried out; there they will attend their classes in civics. And grown men will periodically relearn the laws. Let us conceive of places of punishment as a Garden of the Laws that families would visit on Sundays.

I don't really know what they mean by "intellectuals," all the people who describe, denounce, or scold them. I do know, on the other hand, what I have committed myself to, as an intellectual, which is to say, after all, a cerebro-spinal individual: to having a brain as supple as possible and a spinal column that's as straight as necessary.

Is it surprising that prisons resemble factories, schools, barracks, hospitals, which all resemble prisons?

Discipline 'makes' individuals; it is the specific technique of a power that regards individuals both as objects and as instruments of its exercise. It is not a triumphant power...it is a modest, suspicious power, which functions as a calculated, but permanent economy.

From Plato's Republic... the primary danger of liberty and free speech in a democracy is what results when everyone has his own... style of life... For then there can be no common logos, no possible unity, for the city.

Not only must people know, they must see with their own eyes. Because they must be made to be afraid; but also because they must be the witnesses, the guarantors, of the punishment, and because they must to a certain extent take part in it.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

In France at least, the history of science and thought gives pride of place sciences, sciences of the necessary, all close to philosophy: one can observe in their history the almost uninterrupted emergence of truth and pure reason. The other disciplines, however - those, for example, that concern living beings, languages, or economic facts - are considered too tinged with empirical thought, too exposed to the vagaries of chance or imagery to age old traditions and external events, for it to be supposed that their history could be anything other irregular. At most, they are expected to provide evidence of a state of mind, an intellectual fashion, a mixture of archaism and bold conjecture, of intuition and blindness. But what if empirical knowledge, at a given time and in a given culture, did possess a well defined regularity.

The 'Enlightenment', which discovered the liberties, also invented the disciplines.

Athuroglossos is characterized by..: (1) When you have "a mouth like a running spring," you cannot distinguish those occasions when you should speak from those when you should remain silent; or that which must be said from that which must remain unsaid; or the circumstances and situations where speech is required from those where one ought to remain silent. (2) As Plutarch notes... you have no regard for the value of logos, for rational discourse as a means of gaining access to truth.

This book is intended as a correlative history of the modern soul and of a new power to judge; a genealogy of the present scientifico-legal complex from which the power to punish derives its bases, justifications and rules, from which it extends its effects and by which it extends its effects and by which it masks its exorbitant singularity.

Confession frees, but power reduces one to silence; truth does not belong to the order of power, but shares an original affinity with freedom: traditional themes in philosophy, which a political history of truth would have to overturn by showing that truth is not by nature free--nor error servile--but that its production is thoroughly imbued with relations of power. The confession is an example of this.

A great prison structure was planned, whose different levels would correspond exactly to the levels of the centralized administration. The scaffold, where the body of the tortured criminal had been exposed to the ritually manifested force of the sovereign, the punitive theatre in which the representation of punishment was permanently available to the social body, was replaced by a great enclosed, complex and hierarchized structure that was integrated into the very body of the state apparatus.

My intention was not to deal with the problem of truth, but with the problem of the truth-teller, or of truth telling... [W]ho is able to tell the truth, about what, with what consequences, and with what relations to power. ...[W]ith the question of the importance of telling the truth, knowing who is able to tell the truth, and knowing why we should tell the truth, we have the roots of what we could call the 'critical' tradition in the West.

It is ugly to be punishable, but there is no glory in punishing. Hence the double system of protection that justice has set up between itself and the punishment it imposes.

He who is subjected to a field of visibility, and who knows it, assumes responsibility for the constraints of power; he makes them play spontaneously upon himself; he inscribes in himself the power relation in which he simultaneously plays both roles; he becomes the principle of his own subjection.

In Plato... or Xenophon... we never see Socrates requiring... examination of conscience or... confession of sins. [A]n account of your life, your bios, is... not to give... the historical events... but... to demonstrate whether you are able to show... a relation between the rational discourse, the logos, you... use, and the way... you live. Socrates is inquiring into the way that logos gives form to a person's style of life... whether there is a harmonic relation between the two... the degree of accord between a person's life and its principle of intelligibility or logos... [and] the true nature of the relation between the logos and bios.

The condemned man found himself transformed into a hero by the sheer extend of his widely advertised crimes, and sometimes the affirmation of his belated repentance. Against the law, against the rich, the powerful, the magistrates, the constabulary or the watch, against taxes and their collectors, he appeared to have waged a struggle with which one all too easily identified. The proclamation of these crimes blew up to epic proportions the tiny struggle that passed unperceived in everyday life. If the condemned man was shown to be repentant, accepting the verdict, asking both God and man for forgiveness for his crimes, it was as if he had come through some process of purification: he died, in his own way, like a saint.

The new governmental reason does not deal with what I would call the things in themselves of governmentality, such as individuals, things, wealth, and land. It no longer deals with these things in themselves. It deals with the phenomena of politics, that is to say, interests, which precisely constitute politics and its stakes; it deals with interests, or that respect in which a given individual, thing, wealth, and so on interests other individuals or the collective body of individuals. ... In the new regime, government is basically no longer to be exercised over subjects and other things subjected through these subjects. Government is now to be exercised over what we could call the phenomenal republic of interests. The fundamental question of liberalism is: What is the utility value of government and all actions of government in a society where exchange determines the value of things?

Absurdity destroys the and of the enumeration by making impossible the in where the things enumerated would be divided up.

There is no power relation without the correlative constitution of a field of knowledge, nor any knowledge that does not presuppose and constitute at the same time power relations.

It is a sign of wisdom to be able to use parrhesia without falling into the garrulousness of athuroglossos... One of the problems... how to distinguish that which must be said from that which should be kept silent.

The different pieces of evidence did not constitute so many neutral elements, until such time as they could be gathered together into a single body of evidence that would bring the final certainty of guilt. Each piece of evidence aroused a particular degree of abomination. Guilt did not begin when all the evidence was gathered together; piece by piece, it was constituted by each of the elements that made it possible to recognize a guilty person. Thus a semi-proof did not leave the suspect innocent until such time as it was completed; it made him semi-guilty; slight evidence of a serious crime marked someone as slightly criminal. In short, penal demonstration did not obey a dualistic system: true or false; but a principle of continuous gradation; a degree reached in the demonstration already formed a degree of guilt and consequently involved a degree of punishment.

L'important, c'est que le sexe n'ait pas été seulement affaire de sensation et de plaisir, de loi ou d'interdiction, mais aussi de vrai et de faux. What is important is that sex was not only a question of sensation and pleasure, of law and interdiction, but also of the true and the false.

The chief function of the disciplinary power is to 'train', rather than to select and to levy; or, no doubt, to train in order to levy and select all the more. It does not link forces together in order to reduce them; it seeks to bind them together in such a way as to multiply and use them.

In the Greek conception of parrhesia... truth-having is guaranteed by the possession of... moral qualities... required... to know... and... convey such truth...

The guillotine takes life almost without touching the body, just as prison deprives of liberty or a fine reduces wealth. It is intended to apply the law not so to a real body capable of feeling pain as to a juridical subject, the possessor, among other rights, of the right to exist it had to have the abstraction of the law itself.

In the darkest region of the political field the condemned man represents the symmetrical, inverted figure of the king.

The harmony between word and deed in Socrates' life is Dorian... manifested in the courage he showed at Delium. This harmonic accord... distinguishes Socrates from a sophist... [who] can give... fine and beautiful discourses on courage, but is not courageous... [U]nlike the sophist, he can use parrhesia and speak freely because what he says accords... with what he thinks... [which] accords... with what he does.

The criticism of the reformers was directed not so much at the weakness or cruelty of those in authority, as at a bad economy of power.

All these present struggles revolve around the question: Who are we? They are a refusal of these abstractions, of economic and ideological state violence, which ignore who we are individually, and also a refusal of a scientific or administrative inquisition which determines who one is.

Between the fine point of the brush and the steely gaze, the scene is about to yield up its volume.

But let there be no misunderstanding: it is not that a real man, the object of knowledge, philosophical reflection or technological intervention, has been substituted for the soul, the illusion of theologians. The man described for us, whom we are invited to free, is already in himself the effect of a subjection more profound than himself. A 'soul' inhabits him and brings him to existence, which is itself a factor in the mastery that power exercises over the body. The soul is the effect and instrument of a political anatomy; the soul is the prison of the body.

In... "The Education of Children"... Plutarch gives an anecdote of Theocritus, a sophist, as an example of athuroglossos... he is... "a giant in impudence"... strong not because of his reason, or his rhetorical ability... or his ability to pronounce the truth, but only because he is arrogant. ...His fourth trait is... "putting his confidence in bluster." He is confident in thorubos... the noise made by a strong voice, by a scream, a clamor, or uproar. ...The final characteristic ...his confidence in ..."ignorant outspokenness..." ... it lacks mathesis ...-learning or wisdom.

The public execution is to be understood not only as a judicial, but also as a political ritual. It belongs, even in minor cases, to the ceremonies by which power is manifested.

The appearance in nineteenth-century psychiatry, jurisprudence, and literature of a whole series of discourses on the species and subspecies of homosexuality, inversion, pederasty, and "psychic hermaphroditism" made possible a strong advance of social controls into this area of "perversity"; but it also made possible the formation of a "reverse" discourse: homosexuality began to speak in its own behalf, to demand that its legitimacy or "naturality" be acknowledged, often in the same vocabulary, using the same categories by which it was medically disqualified.

The perfect disciplinary apparatus would make it possible for a single haze to see everything constantly. A central point would be both the source of light illuminating everything, and a locus of convergence for everything that must be known: a perfect eye that nothing would escape and a centre towards which all gazes would be turned.

If there is a kind of "proof" of the sincerity of the parrhesiastes, it is his courage... Saying something dangerous-different from what the majority believes-is a strong indication that he is a parrhesiastes.

It was an important moment. The old partners of the spectacle of punishment, the body and the blood, gave way. A new character came of the scene, masked. It was the end of a certain kind of tragedy; comedy began, with shadow play, faceless voices, impalpable entities. The apparatus of punitive justice must now bite into this bodiless reality.

Exercise is the technique by which one imposes on the body tasks that are both repetitive and different, but always graduated. By bending behavior towards a terminal state, exercise makes possible a perpetual characterization of the individual...It thus assures, in the form of continuity and constraint, a growth, an observation, a qualification.

This dysfunction of power was related to a central excess: what might be called the monarchical 'super-power', which identified the right to punish with the personal power of the sovereign.
